To all whom it may concern:

Be it known that I SeLonx IRWIN (LAW- so.\', a citizen of the ilnited States, residing at Salt Lake City, in the county of Salt Lake, State of Utah, have invented certain new and useful Improvements in Apparatus for Condensing and Puri ing Smoke, &c., of which the following 18 a description, reference being bad to the accompanying drawing, and to the figures of reference marked thereon.

paratus for condensing and purifyirw fumes. smoke or gases, evolved or produce by metallurgical or other furnaces for the purpose of arresting fumes and the particles of solid matter carried in suspension by such fumes. smoke or gases.

While the invention is particularly intended to be used in connection with metallurgical furnaces for the purpose of arresting the particles of metal and metallic material in the form of oxids, chloride, sulfate or other metallic compounds, which would otherwise be carried 05 by the smoke or fumes, and be lost, and subsequently recovering from the material so arrested, the metal contained therein, the invention is ap licable to the treatment of smoke to free it om the particles of carbon or other solid matter carried by it.

In the ordinary operation of roasting or smelting furnaces, it is customary to so operate the apparatus as to avoid, so far as possible, the production of smoke or fumes carrying particles of the. metallic material treated so as to avoid loss. It is the purpose of my invention to so efiectively condense Lea and arrest, the solid materials, however heavily loaded the smoke or fumes may be, thus rendering it possible to so run the smelting or roasting. furnace as to volatilize as fully as ssible the metal of the ore or other matenal treated.

With this object in view, my invention consists in the process of, and apparatus for. condensing and arresting the fumes, and solid articles carried by smoke, fumes or gases hereinafter described, and particularly pointed out in the claims.

Referring to the drawings, the fi its is a verticalsectional view, showing t e apparatus ofzmy invention.

nacc 4 is a vertical pipe, to which the end of the fine or smoke pipe 1 is connected. The up 101' end of the vertical pipe -lis (.Ulk nected y a pipe 5, with the discharge port of a pump 6, which is here shown as a to tar pump, but may be of any usual or con venient form. The. lower end of the vertical pipe 4 terminates a short distance above the surface of the water in a tank '4'. The rerticnl pipe 4 is provided with a cone 8. ex-

5 tending from a point above the end of the My invention relates to processes and api line or smoke pipe 1, and terminating below the said end thereof. Below the lower end of the cone 8, the internal diameter of the vertical pipe is constricted for av short distnncc by means of an internal collar or ring 9, preferably having the opening therethrough tapered from both ends toward the midd e. The cone 8 and the internal ring or collar 9, are so arranged as to leave an annular space 10 about the cone, into which annular space the flue or smoke ipe 1 opens. Below the internal collar or ring 9, the vertical pipe 4 is preferably bent, as shown at 11, to form a zi g passage.

From t e tank 7, a pipe 12.-leads to the inlet port of the pump 6. A chimney or fine 13, preferably surrounds the vertical pipe 4, its walls serving to support the pipes 1 and 5, and to thus support the vertical pipe 4, to which these pi are connected.

n the a o eration of t e apparatus, as above descri ed, the pump being set in operation, draws water from the tank 7 through the pipe 12, and forces it through the pipe 5 and discharges it through the cone 8 into the vertical pi e 4. As the water is discharged through the cone, it tends to form a vacuum in the annular space 10, thus drawing in the smoke or fumes from the furnace through the pi 1. The 'streamof water carries the smo e or fumes with it thro h the internal collar or ring 9, and as the mingled water and smoke pass downward, the fumes and solid matter become thoroughly disseminated and mixed, so that the water is brought"in-contact'with every particle of solid matter, cooling and condensing these particles, and cerr'yin' them with it to the tank-7, the gases freed om solid matter escapiang upward through the flue or chim" ne The water me be circulated until it becomes loaded with the particles of solid lnatter, when 1t, may be allowed to rest te permit the particles of solid matter suspended in it to settle, when the clear water may be drawn 0E, and the sedlment maybe heated for the recovery of the metal containedinit.

The water used may become charged with suif u1w:ms acid or other acids or see, or with soluble salts which may also recovered and utilized.

Having thus particularly described my mvention, what 1 claim as new and desire to secure by Letters Patent isz r i 1. In an apparatus for collecting material carried in suspension by coming from metallurgical furnaces the combinntion with a flue leading fro dt e f urnacenof ag pipe with which said flue communicates, a. tank containing liquid above'thc sin-face of which. said pipe tem'iiinites a il stl'icted portion. in said pipezbelow its with said flue, a cone 1n said pipe op th' siiid connection and'haits'mall a second pi leading from below the surface of the 'quid'in Said tank to the large end of said cone, and -1neans in .said second "of the liquid-in sai mating adjacent to said constricted portion,"

Pipe to force'liquid from said tank into the arge end of said cone.

- flue, a cone in said pipe opposite the said connection ,andhn'ving its small end terminating adjacent to said constricted portion,

a second pipe lending from below the surface tank to the large end of said cone, means in said second p1 e to force liquid from said tanlr into the e end 01;: and a chimney surroun .;,j1IiE8sa1d pipe and Supporting said fine and 'tu e tcstimon jvhereef I aifix my signature,

in presence 0 two'j witnesses.
